Convective heat and mass transfer driven and controlled by turbulence by multifaceted interactions pose ever more new challenges in various branches of engineering, technology and the environment. New insights and discoveries revealed by advanced numerical simulations, laser-based and other novel laboratory diagnostics, both in single- and multi-phase non-reacting and reacting fluid flows, are still awaiting full understanding of the physical phenomena involved, especially of the role of turbulence, its control and manipulation. This Issue of Flow, Turbulence and Combustion aspires to highlight recent progress and to provide an archival record of some of the current trends and achievements in this research field. [...]
